It started because of an odd ad for denture containers, Tooth Garage (for sanitary, safe parking of false teeth), and became one of the gags in Marvin Glass' collection of novelty products (whose gags would include fake vomit [prev], Rock ’Em Sock ’Em Robots, and more [prev] ); usually an inexpensive prank item or toy, but valuable when used as a promotional item for The Rolling Stones: Yakity-yak Talking Teeth, the history.
'It was an instant success,' Stan says. 'It's not surprising, because it meets all the criteria of a good gag. It's very cheap to make, so you could make a decent profit on it.
